This is a little more work than one might think at first sight. For instance,
we do not have virtual machines ready for every kind of database supported by
Ado.Net. It would be great to have them, all along with specialized tests for
all kinds of databases.

Would you like to write a patch for the AdoNetAppender?

> Key: LOG4NET-538
> URL: https://issues.apache.org/jira/browse/LOG4NET-538
> Project: Log4net
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 1.2.15
> Environment: C#
> Reporter: Cristian Margescu
> Labels: patch
>
> I am using the AdoNetAppender to log audits to the database. I was using
> until some time the 1.2.13 version with a configuration for MSSQL or
> PostgreSQL which inserted practically data as json strings that will later be
> interpreted by another tool using the following appender configuration.
> EX: <appender name="NpgsqlAppender" type="log4net.Appender.AdoNetAppender">
> <filter type="log4net.Filter.LevelRangeFilter">
> <levelMin value="AUDIT" />
> <levelMax value="AUDIT" />
> </filter>
> <bufferSize value="1"/>
> <connectionType
> value="Npgsql.NpgsqlConnection, Npgsql" />
> <connectionString
> value="Server={myServer};Port=5432;Database={database};User
> Id={myuser};Password={mypassword}" />
> <commandText value="INSERT INTO audit (message) VALUES (@message);" />
> <reconnectOnError value="true" />
> <useTransactions value="false"/>
> <parameter>
> <parameterName value="@message" />
> <dbType value="String" />
> <layout type="log4net.Layout.PatternLayout" >
> <conversionPattern value="%message"/>
> </layout>
> </parameter>
> </appender>
> It worked great until I have updated to 1.2.15 and then we have noticed that
> the PosgreSQL appender did not worked any more. After doing some research and
> testing I have narrowed it down to the AdoNetAppender
> that probably has a problem with the parameters because it shows a PG error
> 47203 as column "message" not found.
